New, cleaner buses

These buses represent a real benefit for the environment but also for the health of all Ile-de-France residents, not to mention a gain in comfort for passengers.
In 2018, more than 270 clean buses will be on the road in Île-de-France with the aim of achieving 100% clean buses in all the region's dense areas by 2025.
To achieve this objective, Île-de-France Mobilités and RATP launched the largest call for tenders in Europe for the purchase of electric buses at the beginning of 2018.
